If a baking tray is 500mm by 700mm, how many of 25cm in diameter can fit into the oven

First you need to find the area of the baking tray. 500 x 700 = 350,000 mm^2 Next, you must find the area of the "circles" or "cakes". 3.14r^2 3.14(25^2) 3.14(625) 1962.5 mm^2 Finally, you will have to divide the area of the baking tray by the area of the circle/cake. 350,000/1962.5 178.34 cakes So, your final answer will be Approx 178 circles/cakes can fit in the oven. Hope this helps! Cami
